摘　　要：本文以一般弹性杆的纵向振动理论为基础，建立了变截面桩振动参数的计算模式，结合试验结果的分析，研究了桩顶竖向激振力作用下变截面桩的刚度、频率和振幅特性，探讨了影响桩身动力特性的基本因素，为竖向振动荷载作用下变截面桩的设计提供了参考。In the article, based on vertical vibration theory of elastic rods, established calculating mode of vibration parameters for nonuniform piles, made a study of on rigidity. frequency and amplitude charactcristic of nonuniform piles under vertical exciting force on pile top with experimental results, and probed into basic influence factors on dynamic performance of pile body, it may be refrenced for design of nonuniform pile under vertical vibration loading.
